Well, physically yes. You'll be a vampire. But you don't have to be like them. The kind of vampire you become is entirely your choice. I live on blood bags and haven't bitten an actual human in years. I also know a guy who lived on bunny blood for decades which ... would not recommend, because there's a high level of self-loathing that comes with that kind of lifestyle, but there are options.
